.Beitknown that 1, WILLIAM F. LAUTEN-r ..-scnriaean, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Cement- Applying Machines, of which the following is I a specification.

f cement-pot an M -.invent ion relates to cement applying mac es, and is adapted, among other uses,

for applying cement to leather or other fab-.-

rics, tor instance, in the manufacture of shoes and similar articles.

In the present exemplification of my invention I shall describe the same as ada ted" for employment in applying a band 0 cement to the edges of Vamps, or other parts of ap lyin this band of cement being to old the e ge when turned over in the form of a bead, as is'usual in shoe manufacture, and when so employed a viscous very slowly evaporating cement is used.-

Theobjections to applying this cement by hand with a brush are a waste of cement due to the stringing tion on the work of a wider band of cement thannecessary, besides the danger from fire is hi hly inflammable. vice I band of cement of the proper width wit out;

owing to the exposure of the cement, which In my improved deavoid all these objections and ap lya waste of cement and without exposure of the body of cement, While at the same time I retain the benefit accruing from the manneroi .the manual bush-application of the cement.

Objects of m invention are to apply the cement by mac. ine with a motion imitating the motion em loyed in applying thecement with a brush Ey hand; to brush the cement upon the stock by means of a rotary cement feeding brush whose peripheral movement is differentiated from the feed of said stock; to provide a feeding device for the stock and a rotary cement-ap lying brush, with means for causing the stoc -contacting portion of the periphery of the brush proved device.

to trav in the direction of the feed faster than said feed; and to provide improved cement and stock-feeding means; and the invention will be readily understood from the following description and claims, and from the drawings, in whichlatter:

Figure 1 is a front elevation of my im- 2 .isan end elevation of of the cement between the} the worn, and the applicathe same with the cement-cup partly broken away. Fi 3 is a vertical section of the feeding en of my improved device taken on the line 2 20f Fig. 2. Fig. 4 is a plan view of the feeding end of my improved device artly in section on the line "yz of Fig. 5. ig. 5 is an end elevation of the same. Fig. 6 is a..veitical section taken on the line of Fig.-

showing the brushing effect of the brush the cement-application and showing the brush-in end elevation with the feedwheel removed. Fig. 7 is a vertical section of the cement-feeding parts taken on the line 2-2 of Bi 2 and showing the transverse brus ect-of the brush; and, Fi .Sis an enlargesendaelevation of the feedeel and adjacent parts.

l'represents the base fromwhich a preferably goose-neck column 2 extends and which supports a cement-cup 3 which may have a cover 4.

,5 is a table suitably secured to the base. 'Adrive-shaft 6 is 'ournaled in a bearing 7 in theweolumn and "thereon, as a pulley 8.

'9 is an arm depending from the column on which there is a bearing 10 for the driveshaft.-. This arm also has a bearing 11 for an intermediate shaft 12 supporting gears 13 1-4, the gear 13 meshing with a gear 15 on the drive-shaft.

'-. 16 is a sleeve 'our naled loosely about the drive-shaft and carries a gear 17 which meshes with the gear 14.

18 is a cement-applying brush, the bristles of which are mounted in a housing 19 secured to the sleeve 16, as by a screw 20,

gether.

21 is a feed-wheel for the stock, shown at a, the feed-wheel being secured to the shaft 6, as by being mounted on a reduced shank 22 of the shaft, a screw 23 clamping the feedwlieel between the screw and the shoulder 24 on the shaft. The sleeve 16 rotates about the shaft 6, and .for lubricating the same, the screw 23 is provided with a longitudinal bore 25 which communicates with lateral dischar; :-ir-opvnir e 2? extending to the journal 1 on the shaft 6 for the sleeve.

It will be noted from Fig. 8 that the diameter of the applying brush 18 is slightly greater than the diameter of the feed-wheel for purposes hereinafter described. The sizes of the gears 13, 14, 15 and 17 are so as suitable drive means.

-the same related as to drive. the applying-brush at a different speed from the speed of the feedwheel and refer-ably rotating the brush in rection as the feed-wheel, that stock-contacting faces to is, causing their of feed of the stock,

move in the direction also for purposes hereinafter described.

31 is a head in which a cement-feeding roller 32 rotates, the roller being secured to a shaft 33 by a screw 34. The shaft 33 is 'ournaled in bearings 35 36, the bearing 36 eing shown removable as by means of screws 37. A gear 38 is mounted on the shaft33 and meshes with the gear 14. The.

head is supported from the column and has cement-feeding connection with the cement: cup. have shown this accomplished by providing the cupwith a shank 41 secured in a bearing 42 on the column, the head being screwed upon the shank by means of the threaded connection 43 which clamps I rotary vcement-brush, the brush in turn the cement out of the recesses and applying it to the stock. The lip 50 is prov1 ed with a wiping edge 51 rece ing toward the-middle .of the roller, the operation being to direct any cement there may be on the a plying-face 47 after the same has passed t e applyin -brush toward the middle of the applying-face for causing this cement to be received by the recesses, and again fed Wiping through the applying-head, at the same time preventing particles of, leather or dirt from clog ing the applying-roll.

It will ie noted that thebore 45 has a mouth 52 extending toward the feeding por tion or front of the periphery of the rollerand that this mouth is backed by a roof 53 which gradually approaches the roller, the mouth spanning a plurality of the recesses 48, the object being to cause the weight of the cement to bear upon the roller at a plurality of said recesses, the roller in turning carrying the cement with it and the roof forming a wedge for pressing the cement into the recesses of the roller for causing proper filling of the latter and feeding of the cement, and preventing a rolling mo tion of the cement above the roller, it being understood that cement employed for the articular purpose mentioned is liable not to ow freely.

55 is a stock-support which preferably against the'gage.

extends above the plane, of the table and whose stock-supportmg-face 56 ispreferably arranged on a curve from front to rear for readily permitting passage of the goods thereover and reducing the extent of contact between the feed-wheel and applying-brush and the stock. This stock-sup ort is shown on a pin 58 mounted on a lever 57 pivote in bearings 59 on the lower face of the table. The lever has a heel 61 against which a sprin 62 presses, the spring being received in-a bore 63 of an adjusting screw 64 adjustable in'a. threaded bearing 65 of a lug 66 depending from the table, the inner end of the spring being received in a depression 67 of the heel for preventing displacement of the spring, the function of the spring being to urge the stock-support upwardly toward the. feed-wheel stock-support to yield when stock is fed between. the feed-wheel and the support. Toadjustably limit the upward movement of the stock-sup ort I rovide an adjustable set-screw 68 tireaded in the lever and ada ted to strike a lug 69 on the lower face of 516 table. 7 On the stock-support there is a. stock-gage. 70 which I prefer shall be integral with the stock-gage for preventing catching of the bristles of the brush between the stock-support and gage The stock-support operates through an opening 71. in the table. a

In operation, the stock is placed in position on the stock-support for having contact made therewith by the feed-wheel, which thereupon takes hold of the stock for feeding the same through the machine. The feeding periphery of the rolleris preferably provided with cross-ribs 72 and the roller is preferably narrow, the stock-gage 70 being also preferably short for permitting curved edges of stock to be fed through the machine Stock of this kind is usuT it is cut so that its'thickness tapers to a thin edge for ermitting the edge to be readily turnedfbac wardly upon itselfto form a'bead. As heretofore stated the brush is of larger diameter than the diameter of the feed-wheel. The thin skived edge of the stock is received against the ga e, the brush being between the gage and t e feed-wheel for permitting the feed-wheel to act upon a thicker portion of the stock. ihe brush being of greater diameter than the feed-wheel, it applies the cement throughout. the width of the skived portion irrespective of differences in thickness across the. same, as the bristles of the brush give to sufficient extent to contact the stock with the entire width of the brush, as more fully illustrated in Fig. 7. The brush being of larger diameter than the feed-wheel, causes the bristles in their contact with the stock to bend and to y skived, that is,

1 be received within the recessesof the cementfeeding roller. In order that the brush may speed than the feeding speed applied to the stock. I cause a bending of the bristles of the brush from their normal radial positions toward the feeding-in side of the brush and cause these bent bristles to spring rearwardly as soon as they have turned beyond their vertical pos tions at the lower side of the brush. ,11'1' the iormshown I obtain the differential movement at the peripheries of the feed-wheel and cement-ap 1' ing brush while rotating them in the s re direction and by rotating the brush at g eater speed than the feed-wheel. I have found on advisable differential in rotation to be one and a half to one, but this ratio may be departed from or increased or diminished as may be desired without departing from the spirit of my invention. l have indicated the direction of rotation of the brush in the present exemplification of my invention byjhe arrow b, the direction of travel of the stock by the arrow 0, and the direction of rotation of the cementroller by the arrow (Z. v

In order to protect the stock from the gears vent the stock being rawn into the gears I provide the guard 7 3, which is secured to the arm 9 by screws 74 and extends around the bottom and to front and rear of the gears adjacent the brush. T he work-support provided with an outside slope 75 for readily directing the stock to the top of the support.
